 Over the next 11 years Icke wrote "The Robots' Rebellion" (1994), "And the Truth Shall Set You Free" (1995), "The Biggest Secret" (1999), and "Children of the Matrix" (2001), in which he developed his worldview of New Age conspiracism.His endorsement of the antisemitic forgery "The Protocols of the Elders of Zion" in "The Robots' Rebellion" and "And the Truth Shall Set You Free" led his publisher to refuse to publish his books, which were self-published thereafter.Icke believes that the universe is made up of "vibrational" energy and consists of an infinite number of dimensions that share the same space.
